Bayonetta 2 and Wonderful 101 came out originally for the wii-u, the ports for w101 had to be crowdfunded.
There isn't a "port to Switch" button for Wii U games, them remaking 1 and 2 for Switch counts, to say nothing of them actively working on 3 as a Switch exclusive. They also made Astral Chain for Switch, which Nintendo published and advertised heavily in Directs.
You're mostly referencing Nintendo getting companies to make spin-offs for their established IPs. Which is different from what I was talking about which was paying for exclusivity for an already existing series, which Nintendo doesn't really do. The two most major were Monster Hunter and SMT5 and both were released within the last year or so. The Wii-U only had those two like that(unless you're counting 3 Ultimate which was an enhanced port) for it's whole 5 years and for most of the switch's lifespan Nintendo hasn't been doing grabs like that either.
You said "You're not seeing Nintendo throw around money to other companies which is what always has allowed Sony to remain a dominate force in the game industry. Nintendo despite all their earnings don't go around cutting deals with smaller companies and instead just focus on themselves." and thats just not true. Nintendo literally lets other companies develop whole game series using its characters, they publish a boatload of indies which I haven't bothered mentioning previously because fuck 'em, they take quality general audiences JP handheld titles and localize them (no longer relevant with the death of the 3DS.)
As to paid exclusivity, which you seem to be arguing for, and setting aside the idea of "why would you even want that", Nintendo hasn't bothered to do it in the Switch era, which I think you meant to say, because they've sold well enough that people are actively putting games on their systems. They don't have to.
Like there's a difference between paying Falcom for their next game and paying falcom to make a game featuring a crossover IP.
I was talking about the former and how Sony is more willing to do stuff like that with Monster Hunter World, Final Fantasy 7 remake and 16, Persona, and stuff like that. They're way more willing to fund games like that and help pay for the promotional and advertising stuff in exchange for exclusivity arrangements.
Those three game series are also heavily associated with the Playstation brand, in the eyes of a casual gamer they might as well be 1st party IP. Nintendo is "lucky" enough that you could probably count on one hand the number of non-Nintendo IPs that are strongly associated with Nintendo platforms. So they rarely, if ever, have to do stuff like that. And the few times they've tried it, it didn't help their position. Sony seems to be doing it recently to help prop up their own lack of first party games but that is a weakness, not a strength. Thats Xbox circa 2013 and then them wondering why it actually hurts their platform.
As for MH World, I am reading the wiki and Sony definitely helped foot the bill on it, but I am curious what type of exclusivity they had(DLC? marketing?) as the game launched same day on Xbox.
Actually, Google might be fucking me here but I can't find a single thing on Sony/Playstation purchasing Neptunia exclusivity either. Its not on the first few pages of Google returns, its not on the series wiki page OR the individual game's page. Prove it isn't bullshit.
Also, just as a close out. You have said that "Nintendo's national marketshare in japan is a pittance to the global market which is what developers are aiming for." But the PS4+5 have 130 million sales compared to the Switch's 92 million. Take away the fact that Sony had 4 additional years of selling the PS4 that Nintendo did not and those "marketshares" look damn near the same. Its meaningless. You can talk about combined reach of the PS, Xbox and hardcore PC markets. But that, in turn, compares to the three of those plus Switch and mobile, plus budget PCs/cloud. Its a bad argument, developers will tailor their games to whichever group of platforms fits the game series best, unless someone tips the scales, but that rarely happens.
